Try it now...

Delta/absolute mode button: Improved behaviour. 
It behaves exactly like before - abs for one note, delta for more. 
Well, it's about as intuitive as I can make it without another button:
 "LOCK THE MODE".

For some, constant automatic 'suggesting' upon new selections may annoy.
Some may actually instead prefer my rather feeble attempt to keep the 
 user's setting, commented out in PianoRoll::setSelection() around line 668:
	//if(lastSelections <= 1) 
It basically keeps the setting if there are two or more selections.
Alas, if you are manually selecting the notes 1- 2 -3 style, the second click
 still 'suggests' delta mode, but you need simply turn it off and continue 
 selecting - it'll keep the mode.
Also a drawback for some is that it keeps the mode when 'lassoing'
 a new group of notes. Oh well... try it if you like.

Transport and NoteInfo toolbar positional editors: Fixed not updating 
 when tempo or sig changed. 
In PosEdit::setValue(), checking different value is not enough. 
Must check whether resultant msf or mbt values changed.
TODO: updateValue() is now public so it can be called externally but it is 
 not used yet - make NoteInfo and Transport use it instead of setValue().  
A mere technicality. Should work as is with these fixes so far.
